These configuration will let you use CodeLLDB extension to debug Crystal programs.
Store them as .vscode/tasks.json and .vscode/launch.json in your project.
When starting the debugging the current file will be built in the bin/ folder (as in shards build).
Note: You will need to set the crystal binary path in tasks.json "command" field and the whole path in launch.json "initCommands". Read more at #8538

Hello,
I try to start my first Crystal programm. I use Visual Sudio Code in a Windows-Subsystem for Linux Ubuntu 20.04 LTS.
CodeLLDB 1.6.1 is installed
Wenn I start debugging there comes serval errors in the TERMINAL-window:
Executing task: crystal build --debug .vscode/tasks.json -o bin/tasks <
In .vscode/tasks.json:2:6
2 | // See https://go.microsoft.com/fwlink/?LinkId=733558
^
Error: expecting token '=>', not 'See'
The terminal process "/bin/bash '-c', 'crystal build --debug .vscode/tasks.json -o bin/tasks'" failed to launch (exit code: 1).
Terminal will be reused by tasks, press any key to close it.
After removing the remarks in tasks.json and launch.json there is a problem with:
In .vscode/launch.json:10:17
10 | "args": [],
^
Error: for empty arrays use '[] of ElementType'
The terminal process "/bin/bash '-c', 'crystal build --debug .vscode/launch.json -o bin/launch'" terminated with exit code: 1.
Next try after removing args:
Executing task: crystal build --debug .vscode/launch.json -o bin/launch <
/usr/bin/ld: cannot open output file /mnt/c/linux/crystal/firstapp/src/bin/launch: No such file or directory
collect2: error: ld returned 1 exit status
Error: execution of command failed with code: 1:cc "${@}" -o /mnt/c/linux/crystal/firstapp/src/bin/launch -rdynamic -L/usr/bin/../lib/crystal/lib -lpcre -lm -lgc -lpthread /usr/share/crystal/src/ext/libcrystal.a -levent -lrt -ldl
The terminal process "/bin/bash '-c', 'crystal build --debug .vscode/launch.json -o bin/launch'" terminated with exit code: 1.
Do somebody have an idea?
Thanks a lot
Bob
What is the path to
crystal_formatters.py? Is it typically part of a lldb install or a crystal install? Specifically interested in macos, but general advice will do!
